Answer:
we are given that
Student converts grams to milligrams by multiplying by the conversion factor 1g/1000 mg.
we have been asked to find Is the student performing this calculation correctly?
Suppose you have x grams of something and convert it into mg as follows:
As we know that
So we can write
mg
It mean that conversion factor is
It mean student doesn't performed the calculations correctly.
Explanation:
Answer:
Volumes can have the same volume but different masses if they have different densities. For example, a 10 x 10 x 10 block of lead has the same volume as a 10 x 10 x 10 block of pine wood, but the lead block weighs 22.6 times more than the pine block. Indeed, the density of lead is high enough that the lead block will sink in water, whereas the pine block's density is low enough that the pine block will float in water.
Volume is a measurement, the units are cubic metres or cubic centimetres. Litres = 1000 cm3
Mass is a measurement, the units are grams, kilograms.
^^^^^^^^^^^^^^^^^^
to that answer.
Mass is not weight. it is the amount of matter an object takes up. Therefore, saying that a lead block weights 22.6 times more than the pine block does not answer how an object can have different masses but the same volume. :D
Answer:
there should be around 41 moles
Thalidomide is used as a sleeping pill which was deemed to be safe for even pregnant women in its initial manufacture. However, it caused birth defects in several babies and even caused death of the fetus. Today, it is not advised to be taken by women who are pregnant.
